Abstract

In this paper, a novel communication strategy called Power Talk is introduced to realize the power line communication among the Voltage Source Converters (VSC) of DC MicroGrids (MGs). Each VSC transmits information by changing the control parameters, and receives information by observing the local output power. By using common coding schemes, which transform the DC MGs in some familiar communication channels, some important communication challenges can be addressed, such as random load variations and VSCs switching, as it do not need a separate communication channel. For this purpose, two multiple access strategies are analyzed and the method based on training sequences is presented in this paper. Experiments have been carried out on a MG of two parallel converters. The experimental results presented in this paper are to verify the effectiveness of proposed communication strategy.
